I'm attempting to convert a bash idom into fish, and I can't quite  
figure out a clean way to do it. In bash, I sometimes used:

(cd /home/path/to/checkout ; svn diff checkout/path/file.c) | patch -p0

The closest I can come to this in fish is:

begin pushd  /home/path/to/checkout ; svn diff checkout/path/file.c;  
popd; end | patch -p0

Is there a better way?

Thanks,
Nick
